Package "demography" - calculating quintiles of survival probabilities
Hi,
I am using the package "demography" from Rob Hyndman for the
Lee-Carter-Model. It is an amazing powerful tool but I am struggling with
one issue:
*I want to compute different quintiles for the cumulative survival
probability derived from the Lee-Carter-Forecast (e.g. the 50%-quintile,
75%-quintile and 99%-quintile) for the next 10 years. *
I am sure the package possess this

How to do a target value search analogous to Excel Solver
Hi all,
i'm trying to find a solver possibility analogous to the Excel Solver in R.
Since i just started with R, I have only little knowledge. Can someone help
me by solving the problem?
I have the following 'starting position':
z = rnorm(1,0,1)
y <- function(x,z){2*x - 1 + z}
I am looking for a certain "x" in such a way that the result of the function

Package "demography" - calculating percentiles of survival probabilities distribution
Hi,
I am using the package "demography" from Rob Hyndman for the
Lee-Carter-Model. It is an amazing powerful tool but I am struggling with
one issue:
I want to compute different percentiles of the survival probability
distribution derived from the Lee-Carter-Forecast (e.g. the 50%tile,
60%tile, 75%tile and 99%tile) for each of the next 10 years. Is there any
possibility to retrieve
